The 1FK7042-2AF71-1CG0 is a 1FK7 Compact permanent-magnet synchronous servo motor designed for positioning, feeding and speed-controlled machine axes.
It provides a static torque of 3 Nm, a rated torque of 2.6 Nm and a rated speed of 3000 rpm. The motor delivers approximately 0.82 kW at its rated operating point.
The defining feature of this CG0 configuration is its AM24DQI 24-bit plus 12-bit multiturn absolute encoder with DRIVE-CLiQ communication.
This feedback system records both the angular position within one mechanical revolution and the number of completed shaft revolutions within its multiturn measurement range.
The motor is supplied with a plain shaft, natural cooling and no integrated holding brake. Its IP64 configuration is intended for protected machine environments where dust protection and resistance to splashing water are required, but direct water-jet exposure is not part of the installation requirement.
The 1FK7042-2AF71-1CG0 should not be described as a resolver motor. Resolver-equipped 1FK7 configurations use different encoder codes and provide a different feedback principle.

3 Nm Compact Servo Axis
The 1FK7042-2AF71-1CG0 belongs to the 3 Nm static-torque class.
It is suitable for machine functions such as:
- Product feeding
- Label positioning
- Conveyor adjustment
- Small indexing mechanisms
- Printing registration
- Light rotary handling
- Gearbox-driven positioning
The motor should be selected according to the complete torque-speed requirement rather than the 3 Nm static value alone.
Rated and Maximum Torque
Static Torque
3 Nm at 100 K
Rated Torque
2.6 Nm at 100 K
Maximum Torque
10.5 Nm
The maximum torque is available only within the approved current, speed, thermal and drive-system limits.
It should not be described as continuous output torque.
3000 rpm Rated-Speed Configuration
The AF71 winding is configured for a rated speed of 3000 rpm.
This operating point provides a balance between:
- Continuous torque
- Dynamic acceleration
- Machine-cycle speed
- Gearbox input speed
- Thermal loading
- Positioning response
It should be distinguished from lower-speed and 6000 rpm configurations in the same motor family.
AM24DQI Multiturn Encoder
The motor uses an AM24DQI absolute encoder with:
- 24-bit resolution per revolution
- 12-bit multiturn revolution measurement
- DRIVE-CLiQ communication
- Absolute rotor-position feedback
- Electronic motor identification
The 24-bit single-revolution resolution represents more than sixteen million positions within one mechanical turn.
The 12-bit multiturn range records up to 4096 revolutions within the encoder measurement range.
Absolute Position Feedback
The multiturn encoder supports machine axes that require position information after control-power interruption.
Depending on the mechanical transmission and control project, this can help reduce or eliminate repeated homing.
Typical functions include:
- Absolute rotor-angle detection
- Revolution counting
- Speed feedback
- Position feedback
- Motor commutation
- Direction monitoring
The actual machine position still depends on the configured gear ratio, axis parameters and mechanical connection.
Not a Resolver Motor
The 1FK7042-2AF71-1CG0 does not use resolver-based feedback.
AM24DQI Encoder
High-resolution digital absolute feedback
Multiturn position measurement
DRIVE-CLiQ communication
Resolver Feedback
Analog sine and cosine feedback principle
Lower-resolution but robust feedback architecture
Different motor order-number configuration
These encoder systems should not be described as interchangeable.
DRIVE-CLiQ Integration
The encoder communicates with the compatible drive controller through DRIVE-CLiQ.
Typical functions include:
- Automatic motor recognition
- Electronic nameplate transfer
- Encoder-data communication
- Temperature-data transmission
- Parameter assignment
- Drive diagnostics
- Topology identification
A compatible Motor Module, Control Unit and approved motor cable are required.
Plain Shaft Configuration
The motor has a plain shaft rather than a keyed shaft.
It is suitable for:
- Clamping couplings
- Bellows couplings
- Shrink-disc connections
- Low-backlash gearbox inputs
- Precision direct-coupled loads
A plain shaft can provide concentric coupling and balanced rotation when installed correctly.
No Integrated Holding Brake
The 1FK7042-2AF71-1CG0 does not include a holding brake.
It is best suited for:
- Horizontal axes
- Mechanically self-locking systems
- Applications with an external brake
- Axes that do not need holding torque after shutdown
Vertical or suspended loads require a separate validated holding arrangement.
IP64 Protection
The motor has an IP64 degree of protection for the applicable standard configuration.
IP64 indicates protection against:
- Dust ingress
- Splashing water from different directions
It does not indicate protection against direct water jets or immersion.
Correct protection also depends on:
- Properly fitted connectors
- Approved motor cables
- Correct shaft sealing
- Cable-entry orientation
- Complete machine installation
IP64 vs IP65 Version

These models are similar electrically, but their protection configuration differs. The exact suffix must be matched when replacing a motor.
Natural Cooling
The motor dissipates heat through its housing and mounting flange without an external fan.
Reliable operation requires:
- Firm flange mounting
- Adequate heat transfer
- Unobstructed airflow
- Approved ambient temperature
- Correct drive parameters
- Operation within the torque-speed curve
The motor should not be described as separately fan-cooled.
Motor and Drive Integration
A complete servo axis normally includes:
- Compatible Control Unit
- Motor Module
- Line or power-supply module
- Motor power cable
- DRIVE-CLiQ feedback cable
- 1FK7042-2AF71-1CG0 motor
- Mechanical coupling or gearbox
- Approved motor parameters
The 600 V DC specification describes the compatible drive-system DC link. The motor must not be connected directly to a 600 V DC supply.
